This inventionrelates to egg candling apparatus, and particularly tonovel means whereby a; dark room may: be lighted-intermittently for the:purpose of displaying crates ofi eggs, or their contents, and wherebythe lighting apparatus may be operated to: interrupt; the passage -oflight tothe dark room while eggs selected from the cratesare beingcandled, novel means being provided for operating the light" controllingmeans and the candling mask, the said in- Y vention including novelmeans whereby the light shutter and the candling mask are operated inunison.

It is a further object of this invention to provide a candling apparatuswhich can be expeditiously manipulated for the purposes intended andwhich has advantages in points of simplicity and efiiciency, the samebeing comparatively inexpensive to manufacture.

With the foregoing and other objects n view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application, wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a view in elevation of an egg candlerembodying the invention;

Figure 2 illustrates a sectional view on the line 22 of Fig. 1; and

V Figure 3 illustrates a view in elevation of the device with the partsin diflerent positions from that in which they appear in Fig. 1.

In these drawings 5 denotes a hollow bracket which may be suspended orsupported in any appropriate way, and the bracket terminates in a hoodor casing 6. It is intended that electric conductors shall be extendedthrough the bracket to the interior of the casing where electric lampsmay be employed for lighting the interior of the hood, although, ofcourse, under certain conditions, other illuminating means may besupplied within the hood. The lower end of the hood or casing isprovided with a door or shutter 7 having one of its edges hinged, as at8, to the hood in order that the said shutter may swing down- 1927.senar No. 204,815.

wardly and "upwardly, as h indicated by the arrow in Figml.

A bracket 9 extends from the hood or casingf'and a bearing 10 is formedon its outer end, the said bearing constituting a support for a pin orshaft 11 which may rotatein the bearinguAn alrm.12 carries oris attachedto. thepin or shaft 11 andthe end of the arm remote from the bearing isprovided with a connection 13 which is attached to the shutter,.as1shown in Fig. 2,

so that asthe arm oscillates, the shutter is moved to a closed or openposition, according to the direction of movement of the arm.

The arm is provided with an angularly disposed extension 14 to which aflexible or other element 15 is attached and this element 15 isconnected to an arm 16 of a mask 17 which is oscillatably mounted on apivot 18 on the side of the casing. The mask is shown as havingapertures such as 19 to which eggs may be applied during the candlingprocess, and the apertures of the mask are in alinement with an aperture20 in the casing so that light in the casing may be observed through theapertures of the mask and the aperture 20 of the casing.

From an inspection of the drawing and the foregoing description, it willbe apparent that in operation, the room in which the candler isinstalled and which may contain eggs in crates or containers, may beprovided with light when the shutter 7 is opened in order that thecontents of the container may be observed, and that when eggs areselected from the containers which are to be candled, they will beapplied to the apertures of the mask and pressure exerted on the mask tomove the mask into position concentric with the external surface of thecasing, which movement will impart movement to the shutter through thearm and its connection so that light will not issue from the bottom ofthe casing. When this condition exists, there will be no light in theroom, and hence, eggs which are applied to the apertures of the mask maybe observed and, of course, if they are unimpaired, the light that iswithin the casing may be distinctly observed, whereas if the eggs arenot fresh, the light would be obscured or obstructed, so that by thismeans, the operator during the candling process may be provided withintermittent illumination in the room and it will be intermittentlyinterrupted in order that it will not interfere with the candlingoperation.

I claim:

1. In a candling device, a casing adapted to have a source of light, thesaid casing having an openin in its wall, a shutter hinged to the casingat its lower end for opening and closin the said casing, an aperturedmask movab mounted with relation to the aperture of t e casing andadapted to guard and ungniard the aperture, and means for communicatingthe motion of the mask to the shutter.

2. In a candling device, a casing adapted to have a source of light, thesaid casing having an opening in its wall, a shutter hinged to thecasing at its lower end for opening and closing the said casing, anapertured mask movably mounted with relation to the aperture of thecasing and adapted to guard and unguard the aperture, an arm on the saidmask, an arm pivotally mounted with relation to the shutter, means forconnecting the second mentioned arm to the 25 shutter, and means forcommunicating the motion of the first mentioned arm to the secondmentioned arm.

3; In a candlin device, a casing ada ted to have a source 0 light andhaving a s ut- 30 ter for opening and closing the casing, a devicethrough which light may be admitted to eggs being candied, and means forimpartlng the motion of said means to the prevent light from emanatingfrom the casing, an illuminating means associated 40 with the casing,and means for imparting motion of the egg illuminating means to themeans for closing the opening in the casing. 1 1
